A system for supplying power with a combustion engine includes an engine having fuel and air intake lines, and an exhaust line. The engine has a combustion chamber volume defining a number of liters of engine displacement. A fuel cell has a gas outlet that communicates with the air intake line, and selectively produces hydrogen and oxygen gases through an electrolysis process. An oil pressure sensor communicates with the engine to sense when the engine is operating. A switch communicates with the sensor and is closed when the sensor senses that the engine is operating. The switch is open when the sensor senses that the engine is not operating. A battery communicates with the fuel cell and selectively supplies electrical power for the electrolysis process when the switch is closed.

Exhaust emission control is exercised to restrict the exhaust amounts [g] of HC, CO, NOx, and the like. However, since the intake air amount for startup unduly increases due to an engine speed overshoot for startup, the exhaust amounts of HC, CO, and NOx increase excessively. Therefore, there is a need for optimizing the intake air amount for startup. The present invention proposes an engine startup control method that assures excellent startability and low exhaust emissions (small gas amount). Disclosed is an engine control device for starting an engine (from its stop state). The engine control device includes a section for setting a target engine operating state of each combustion; a section for detecting an actual engine operating state of each combustion; and a section for computing a control parameter for each subsequent combustion in accordance with the target engine operating state of each combustion and the actual engine operating state of each combustion.

An engine capitalizes on the advantages of alternative fuels such as ethanol, E-85, and other alcohols, with a small displacement engine, two cylinders or more, and at least a divided fuel tank or alternatively two tanks. An electronic engine control module selects the fuel for operating conditions and delivers the fuel through separate injection systems. The module selects unleaded gasoline for starting, light load and light cruising conditions. Upon greater demands for engine power, the module adds or switches entirely to a secondary fuel such as alcohol, ethanol, E-85 or other ethanol/gasoline blends and reduces or eliminates the introduction of gasoline fuel. The secondary fuel provides more power than unleaded gasoline, thus reducing the engine displacement required for operating a vehicle under a variety of loads. The present invention seeks a substantial engine power increase, reduction in engine detonation, improved cold starting, re-evaluation of turbochargers, a decrease in gasoline consumption, and gasoline as the default fuel.

The engine control system allows a small and efficient engine to deliver increased power upon demand over conventional automotive engines. The system modulates boost pressure when using a secondary fuel for operations at an increased power level. The power level increase occurs from the combination of lower stoichiometric, or higher octane, fuel and increased dynamic intake pressures. The system maintains engine power as low, with little or no intake boost pressure, and the gasoline, 85 octane minimum, is delivered through injectors. When higher power is demanded, the system increases boost pressure, at intake, while a secondary power fuel (ethanol, E-85, alcohol and the like), is injected.

A mechanism based on time control for opening the gas inlet valve of piston compressor is composed of external and internal barrels and an internal rotary axle. The continuous pressure oil coming from oil supply system is regulated by an oil pressure distributor to become pulsive pressure oil and then outputted via oil outlet. The axial movement of internal sleeve barrel can change the relative position of oil outlet to oil pressure acting region and in turn the hydraulic action time and durable open time of gas inlet valve. The longer the open time, the more the gas refluxes in cylinder and the less the gas to be actually compressed, so changing the displaced volume of compressor in stepless mode.
